This study analyzed the prognostic significance of age in patients with intrahepatic cholangiocarcinoma (ICC). Cases diagnosed with ICC between 1988 and 2009 were extracted from the Surveillance, Epidemiology and End Results (SEER) database as the primary cohort. The enrolled patients were divided into 2 groups: the elderly group (≥ 65 y of age) and young group (<65 y of age). The 1, 3 and 5-y cancer-specific survival (CSS) rates were obtained. Kaplan-Meier curves were applied and multivariable Cox regression models were built to analyze the risk factors for prognosis. A multifactorial, integrative nomogram for prognostic prediction was formulated by software R. Cases diagnosed in 2010 from the SEER database were enrolled as the validation cohort. In total, 2161 patients were ultimately included in the primary cohort. The 1, 3 and 5-y CSS rates were 34.3%, 12.5% and 6.5% in the elderly group and 49.8%, 21.3% and 11.5% in the young group, respectively. Univariate (P=0.001) and multivariate (P<0.001) analysis revealed a significant difference in CSS between the two groups. Clinical variables including age, pathological grade, primary tumor stage, lymph node invasion and metastasis were integrated to formulate the nomogram for prognostic prediction, and its predictive power was higher than that of conventional TNM staging. The results were confirmed in the validation cohort. In conclusion, aging could provide important prognostic information for ICC patients and further serve as a critical stratification parameter for the choice of treatment.
Background: Coronavirus disease 2019 (COVID-19) is a global pandemic. Breast cancer is the most commonly diagnosed malignant cancer in China. Considering the specific national conditions, no evidence is available for factors associated with COVID-19 vaccination in patients with breast cancer.Methods: This was a cross-sectional survey, fielded from June 21 through June 27, 2021. A total of 944 nationally representative samples of Chinese breast cancer patients participating in the survey were included. Participant surveys included questions addressing who finished COVID-19 vaccination with the question "Have you taken the COVID-19 vaccine?", and response options were "Yes" and "No".Results: Overall, 730 (77.33%) women with breast cancer were unvaccinated, and only 214 (22.67%) were vaccinated with the COV-ID-19 vaccine. After adjusting for potential confounders, including both sociodemographic and clinical characteristics, we found that external support, including positive doctor suggestions (odds ratio (
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
